Meh, overall it's a problem with America's litigation society where "nothing's your fault." The parents of the 8-year-old has some major explaining to do, letting someone that young try to fire off a submachine gun (And this is an Uzi, real Israeli Uzis are big, not hand-sized like the MAC-10). We've got both a 15-year-old handing off a weapon to a younger kid, we've also got, what I'm going to consider the owners of the booth, letting a 15-year-old hand an automatic weapon to an eight-year-old, and if he wasn't at a booth, then why the hell are you letting your kid around some strange teenager with a bunch of guns? No, we've got a cluster of incredibly stupid people who need to be removed from the breeding pool.
But instead, we're going to blame the hunk of metal on the problem. That's right, like we blame an inanimate object for doing something, or better yet, we'll blame "The gun society" for our issues, something that's merely an abstract construct, something that doesn't exist in our life. People seem to completely disregard their own free-will when its convenient to them. Do I blame the 8-year-old? No, he's 8, guns are seen as cool, a source of power, and the worst thing that'll happen when they go off is either someone gets black soot all over their face, or they poof and need a respawn later. The teenager? A bit more blame, certainly, but at the same time, where the hell are his parents? But, in the end, where the hell are the 8-year-old's parents? You're letting someone like that wander around a place with dangerous items, and a whole bunch of people who, obviously, are not exactly the brightest bulbs in the shed (the gun jammed twice according to the article, hey, bub! First time it jammed, I think that's a good sign you ought to put that thing away until you clean it later). But, ah well, the parents are blaming the teen for their bad parenting, and then the larger society blames abstractions because they don't want to think of themselves as being stupid.
Hey, I'm sad the kid's dead, and I'm sorry for the parents, but, you know, someone was a bit stupid here.
